Although the Four Tops made their biggest mark with Motown, throughout their 43-year partnership -- they hold the record for most years together by original members of a pop group -- the Tops have displayed an amazing range that transcended the polite pop of Berry Gordy's legendary label. The lion's share of material featured on this expansive four-disc set draws on the quartet's Holland-Dozier-Holland-penned classics, including "I Can't Help Myself (Sugar Pie, Honey Bunch)," "Reach Out I'll Be There," and "Bernadette." Those interested in the group's lesser-known beginnings, however, will be pleasantly surprised by early '60s singles such as the doo-wop flavored jazz of "Could It Be You" and the more sophisticated Mills Brothers-like harmonies of "Until I Met You." Post-Motown, the Tops broadened their scope, shifting easily between funk, pop, and disco while scoring smashes with songs such as "Ain't No Woman (Like the One I've Got)," "Keeper of the Castle," "When She Was My Girl," and "Indestructible." Equally intriguing are notable nuggets such as the moving ballad "I Believe in You and Me" (later a hit for Whitney Houston on the Preacher's Wife soundtrack) and a live version of "Midnight Flower" driven by lead singer Levi Stubbs's testifying growl. As if the familiar hits weren't enough, nearly half of the 85 songs on this handsome set are making their debut on CD (10 were previously unreleased). The box also includes a deluxe 84-page booklet packed with rare photos and interviews with the group's surviving members and producers. Four Tops fans and soul diehards will find plenty to sink their teeth into on this thorough compendium of classics.
